APPARATUS FOR REMOVING PAINT.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed June 25, 1907. Serial No. 380,792.

To all whom it may concern:

Be it known that I, JOSEPH HENDRIK STORM, J r., citizen of Holland,subject of the Queen of Holland, residin at Amersfoort, in the Kingdomof the Netherlands, have invented certain new and useful Improvements inAp aratus for Removing Paint, of which the fo owing is a full, clear,and exact description.

The object of the present invention is the provision of a novelapparatusfor removing paint adhering to Wood or metal articles 2. 9.doors, windows and the like The method is characterized by the fact thatthe loosening of the paint is not achieved by the heat-- ing of an openflame but by indirect heating effected by means of the radiated heat ofaheating-apparatus provided with a scraper.

Up to the resent the removal of the aint has been adhieved by heatingthe o ject which has to be cleaned from paint by an open flame andafterwards treating it with a This method has several disadvantages.First, the treatment of the wood or other object to be cleaned frompaint by an open flame involves constant danger of fire; then the heatedlace frequently became cool before the p treated by the scraper. Anotherdisadvantage is that the wood often catches fire or gets partly charredso that thepaints difluse a disagreeable smell.

The present invention obviates these objections as the heating iseffected by the radiating heat of this scraping-apparatus, so

that the heating and scraping are executedby a single 0 eration. Theradiated heat is not sufficient y concentrated to set fire to the woodor to char it. a soft substance without making a smell.

In the accompanying drawings, the apparatus is shown.

Figure 1. is a part sectional elevation; Fig. 2. is a side view, on areduced scale in cona reservoir containing the combustible or fuelattached to the beltof the workman; while Fig. 3. shows a modificationof the fastening device.v

The apparatus is made of sheet-iron or ace in question was It reducesthe paint to 0 certained the nature of my said inventlon 'be scrapedfrom the other suitable metal, and consists of a casing 1, to which at aconvenient place the scraper 2 is secured. The burner 5 for the heatingof the scraper 2 is fitted in the interior of the caslng.

The wall of the casing 1 is provided with openings 4. for the supply ofair for combustion and for the outlet of combustion products. The supplyof the combustible fuel to the scraper is conducted by means of the tube8 from acontainer or generator 11 for the combustible, thus allowingfree movement of the scraper. Acetylene, gas, petroleum, electriccurrent, or any other suitable heating medium may be employed.

The heating appliance, for instance an acetylene generator, tain casesat the belt of the workman (Fig. 2), so that the generator and thescraper in this manner always remain independent of each other, anddirect contact between the doors, windows, articles of furniture or thelike and the fire is out of the question. The heating of the tool orlike scraping-device is effected by the nozzle or burner 5 arranged inthe interior (1) of the scraper and connected with the supply-tube.

In the drawing, 6 represents the securing plates for fixing the scraper2.

7 is the part to be treated for example, a painted door; 9 anadjustingscrew'for olding the scraper.

3 and 10 are handles.

The combustible matter escapes from the tube through the burner or thelike 5.

In the forrri shown in Fig. 3, the scraper 2 is screwed in thetool-holder by means of the screw 12.

Having now particularly described and asand in what'manner the same isto be performed, I declare that what I claim is:-
